Abstract: A muscle control device includes an electromyography (EMG) electrode unit including a plurality of electrodes, and that senses an EMG signal, an EMG circuit unit that generates channel data, based on electrode signals, a control unit that receives the channel data, extracts a volitional electromyography signal, based on the channel data, and determines FES (Functional Electrical Stimulation) stimulation parameters, based on the volitional electromyography signal, an FES electrode unit that outputs a functional electrical stimulation, based on the FES stimulation parameters, and an FES circuit unit that receives the FES stimulation parameters, generates the functional electrical stimulation, based on the FES stimulation parameters, and transmits the functional electrical stimulation to the FES electrode unit, and the control unit recognizes a direction and an intensity of a motion from the volitional electromyography signal, based on the volitional electromyography signal and adjusts an intensity of the functional electrical stimulation.

Abstract: A method of updating firmware of a router and a terminal node in a multi hop-based IoT wireless network system including an access point, routers, and terminal nodes, the access point, the router, and the terminal node each functioning as an OTA master in the case of a parent node, and functioning as an OTA slave in the case of a child node, the method including: determining whether the OTA master is ready to download firmware of the OTA slaves connected to the OTA master;
downloading firmware data to the OTA slave that is ready to download the firmware in units of blocks; determining firmware data blocks that need to be resent, to resend and download the firmware data blocks to the OTA slave; and when the OTA master determines that resending the firmware data blocks is completed, determining that firmware download of all the OTA slaves is completed.
